Technical Field
[0001] This invention belongs to the field of petroleum machinery and equipment technology, specifically relating to a root-establishing device with roller clamping and lifting function for tubing. Background Technology
[0002] During drilling, after the tubing string is transported from the surface to the drilling platform, a tubing string establishment operation is required. The conventional automated tubing string drilling rig generally uses the following establishment process: the tubing string is transported from the surface to the drilling platform via a power catwalk; the end of the tubing string is engaged by a power clamp at the lower end of the top drive; a buffer manipulator mounted on the derrick extends to support the lower end of the tubing string, pulling it vertically from the catwalk and inserting it into a mouse hole, where the mouse hole holds the tubing string. Using the same process, the top drive, with its clamp, pulls up another tubing string from the catwalk; the clamp holds this second tubing string and connects it to the tubing string in the mouse hole; a steel driller on the drilling platform extends to the mouse hole and threads the two tubing strings together at the joint, forming the tubing string stand. The disadvantages of this tubing string establishment operation are: the operation requires numerous processing devices and has a complex control process; the sequential execution of the establishment process results in low processing efficiency; and the establishment operation occupies the top drive equipment, a critical piece of equipment for normal drilling, thus affecting normal drilling operations. Summary of the Invention
[0003] The purpose of this invention is to provide a root-establishing device with roller-clamped tubing lifting function, which solves the problems of multiple processing devices, complex control processes, low processing efficiency, and impact on normal drilling in the prior art.
[0004] The technical solution adopted in this invention is: a root-establishing device with roller clamping and lifting function for pipe columns, comprising a mounting frame formed by two longitudinally parallel main beams and a crossbeam between them, an upper clamping and lifting device is mounted on both sides of the main beams of the mounting frame, a lifting hydraulic cylinder I is hinged longitudinally to the upper clamping and lifting device and fixed at the other end to the mounting frame, a lower clamping and lifting device is fixedly mounted on both sides of the main beams of the mounting frame, a fixed iron drill is set on the crossbeam of the mounting frame, a mounting seat I is fixedly mounted on one side of the main beam of the mounting frame, a pipe-supporting manipulator is set on the mounting seat I, and a support leg is set at the bottom of the mounting frame.
[0005] The invention is further characterized in that, The upper clamping lifting device consists of two symmetrical clamping devices connected by a connecting frame. Each clamping device includes a bracket with traveling rollers that contact the main beam of the mounting frame.
[0006] Both supports are equipped with horizontal sleeves on their adjacent sides. Each sleeve is connected to a roller assembly via a sliding rod. Each roller assembly is hinged to a clamping cylinder I on the same side support at the other end.
[0007] The roller assembly includes a mounting base II fixed to the slide bar. The bottom end of the mounting base II is connected in sequence to a load cell and a bearing housing. The bearing housing is fitted with a bearing, and a mounting shaft is installed inside the bearing. The shaft is connected to a diamond-shaped roller via a key, and one end of the shaft is externally connected to a hydraulic motor.
[0008] The pipe-supporting robot includes a rotary device, which includes a rotary support fixed on the mounting base I. A rotary disk is installed on the rotary support. Edge teeth are provided on the side wall of the rotary disk in the circumferential direction. One side of the rotary disk meshes with a gear A through the edge teeth. A hydraulic motor coaxially connected to the rotary support is connected to the gear A.
[0009] The pipe-supporting robot also includes a guide rail frame set vertically on a rotary table, with a main arm embedded in the guide rail frame. A lifting hydraulic cylinder II is hinged longitudinally on the main arm, with its other end fixed to the guide rail frame. The top of the main arm is rotatably connected to a telescopic arm via a telescopic arm rotation drive device, and the other end of the telescopic arm is fixedly connected to a pipe-supporting wrench.
[0010] The telescopic boom slewing drive device consists of a motor connected to a planetary reducer, which in turn is connected to a slewing reducer. The planetary reducer is fixed on the main boom, and the slewing reducer is connected to the telescopic boom. The motor drives the slewing reducer to rotate through the planetary reducer, which in turn drives the telescopic boom to rotate along the main boom.
[0011] The pipe wrench includes a clamp frame fixed to the telescopic arm, with clamping cylinders II hinged at symmetrical positions on both sides of the clamp frame. The other end of the clamping cylinders II is hinged to the jaws that are hinged to the clamp frame via a pin. When the clamping cylinders II extend, they drive the jaws on both sides to clamp the pipe column.
[0012] Roller I is hinged between the two sides of the clamp frame by a pin, and ear plates are arranged on the jaws by a pin hinged to roller II. Both roller I and roller II are made of nylon material.
[0013] The fixed iron drill includes a gantry frame installed on the crossbeam of the mounting frame, a rotary clamp installed on the upper part of the gantry frame, shock-absorbing springs installed at the connection points between the rotary clamp and the gantry frame at both ends, and a punch clamp installed on the lower part of the gantry frame.
[0014] The beneficial effects of this invention are as follows: The pipe-setting device with roller clamping and lifting functions solves the problems of multiple processing devices, complex control processes, low processing efficiency, and impact on normal drilling in existing technologies. The vertical pipe delivery robot grabs the pipe string from the drill pipe box and transports it to the pipe-setting device. The pipe-setting device, through functions such as clamping, lifting, attaching / unattaching, and pipe support, establishes the pipe string. This device has a high degree of functional integration, enabling a single device to complete the pipe string connection and disconnection work, thus improving processing efficiency. Through local operation and remote operation by the driller, the vertical pipe delivery robot, vertical drill pipe box, and pipe-setting device are linked for automated control.

[0017] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.
[0018] This invention provides a root-establishing device with roller-clamping and lifting function for establishing 8 vertical roots of a tubing column, such as... Figure 1 , 2As shown, the system includes a mounting frame 1. Upper clamping and lifting devices 2 are mounted on the main beams on both sides of the mounting frame 1. Lifting cylinders I7 are symmetrically connected to both sides of the mounting frame 1 via lugs and clamps. The other end of each lifting cylinder I7 is hinged to the upper clamping and lifting device 2. The extension and retraction of the lifting cylinder I7 causes the upper clamping and lifting device 2 to slide up and down the mounting frame 1. Lower clamping and lifting devices 5 are fixed to the main beams on both sides of the mounting frame 1 via lugs. A fixed iron drill 4 is installed on the crossbeam of the mounting frame 1. A mounting seat I6 is fixed to one side of the main beam of the mounting frame 1 via a lug, and a pipe-supporting manipulator 3 is installed on the mounting seat I6. Support legs 9 are installed at the bottom of the main beams on both sides of the mounting frame 1. The length of the support legs 9 is adjusted by screws, and the feet touch the ground.
[0019] like Figure 3 As shown, the upper clamping lifting device 2 consists of two symmetrical clamping devices, including a bracket 11. The bracket 11 is connected to the connecting frame 14 via an ear plate, connecting the two clamping devices into a whole. A roller assembly 10 is inserted into the sleeve at the front end of the bracket 11. The roller assembly 10 consists of upper and lower rollers forming a single structure. One end of the clamping cylinder I 13 is hinged to the bracket 11, and the other end is hinged to the roller assembly 10. The extension of the clamping cylinder I 13 drives the two roller assemblies 10 to extend out and clamp the column 8. The traveling roller 12 is connected to the fixed bracket 11 via bolts and nuts. The traveling roller 12 contacts the main beam of the mounting frame 1 and slides up and down on the main beam of the mounting frame 1. Figure 4 As shown, the roller assembly 10 includes a mounting base II 18, which is embedded in the bracket 11. The mounting base II 18 is connected to a bearing housing via a weighing sensor 19. The bearing housing is fitted with a bearing and is installed in conjunction with a shaft 16. The shaft 16 is connected to a diamond-shaped roller 17 via a key. A hydraulic motor 15 is connected to the shaft 16. The rotation of the hydraulic motor 15 drives the shaft 16 to rotate, which in turn drives the diamond-shaped roller 17 to rotate. The diamond-shaped roller 17 has a circular arc groove in the middle and a diamond pattern on the outer side to reduce damage to the outer layer of the tubing string 8. The weighing sensor 19 can convert the clamping force of the roller assembly 10 on the tubing string 8 into a measurable electrical signal according to a certain ratio and output it to the driller's room for display.
[0020] like Figure 5As shown, the pipe-supporting robot 3 includes a rotating device 26, which includes a rotating support fixed to the mounting base I6. The rotating device 26 also includes a hydraulic motor and a gear A connected together. The hydraulic motor is fixed to one side of the rotating support, and the gear A meshes with the edge teeth of the rotating disk on the rotating support. The hydraulic motor drives the gear A to mesh with the rotating disk, and the rotating disk rotates, causing the equipment on it to rotate. A guide rail frame 24 is vertically arranged on the rotating disk of the rotating device 26. The main arm 23 is inserted into the guide rail frame 24. The guide rail frame 24 is fixed to the lifting cylinder II 25 by the lug and the clamp. The other end of the lifting cylinder II 25 is hinged to the main arm 23. The extension and retraction of the lifting cylinder II 25 causes the main arm 23 to slide up and down within the guide rail frame 24. The telescopic boom 21 rotates along the main boom 23 via a slewing drive device 22. The slewing drive device 22 consists of a motor connected to a planetary reducer, which in turn is connected to a rotary reducer. The planetary reducer is fixed to the main boom 23, and the rotary reducer is connected to the telescopic boom 21. The motor drives the rotary reducer through the planetary reducer, thereby causing the telescopic boom 21 to rotate along the main boom 23. The front end of the telescopic boom 21 is connected to the pipe clamp 20 via a pin. The telescopic boom 21 consists of two telescopic boom sections. Figure 6 As shown, the pipe wrench 20 includes a frame 27, which is connected to the telescopic arm 21 by a pin. The frame 27 is symmetrically positioned on both sides and hinged to a clamping cylinder II 29 via lugs. The other end of the clamping cylinder II 29 is hinged to jaws 30 via lugs. The jaws 30 are hinged to the frame 27 by a pin. When the clamping cylinder II 29 extends, it causes the jaws 30 on both sides to clamp the pipe string 8. The frame 27 is hinged to roller I 28 by a pin. Lugs on the jaws 30 are hinged to roller II 31 by pins. Rollers I 28 and II 31 can rotate freely and are made of nylon. The pipe wrench 20 ensures that the pipe string 8 will not come out of the wrench head and also allows the pipe string 8 to slide up and down and rotate, serving as a guide for the pipe string 8.
[0021] like Figure 7 As shown, the fixed iron drill 4 includes a gantry frame 32, which is mounted on the crossbeam of the mounting frame 1. A rotary clamp 33 is installed on the upper part of the gantry frame 32. Shock-absorbing springs 35 are added at the connection points between the rotary clamp 33 and the gantry frame 32 to prevent the clamp from popping out after the pipe column 8 is loosened. The shock-absorbing springs 35 play a shock-absorbing role. A punch clamp 34 is installed on the lower part of the gantry frame 32.
[0022] The structure of the lower clamping lifting device 5 is similar to that of the upper clamping lifting device 2, except that the traveling rollers 12 are removed and the device is fixed to the mounting frame 1 by ear plates.
[0023] Mounting frame 1 is a portal frame with an open front, comprising two longitudinally parallel H-beams. Several crossbeams are located at the rear between the two main beams, connecting the H-beams on both sides to form an integral frame. The upper and lower crossbeams are connected to the ear plates of the drilling rig base via lugs. A fixed iron drill bit 4 is installed, with supports between the upper and lower crossbeams.
[0024] like Figure 8 As shown, the working process of the root-establishing device with roller-clamping and lifting function of the present invention is as follows: The entire device of this invention is suspended along the center line of the wellhead on the front side of the base, with holes pre-drilled in the ground at corresponding positions to accommodate the length of the tubing string 8. The support platform on the upper side of the base and the connecting frame at the lower end are connected to the upper and lower crossbeams of the mounting frame 1 respectively through pins and lugs, and the support feet of the outriggers 9 touch the ground. The vertical tubing gripping manipulator grabs the tubing string 8 from the drill pipe boxes on both sides and transports it to the tubing string establishment device. The telescopic arm rotation drive device 22 of the tubing manipulator 3 drives the telescopic arm 21 to rotate along the main arm 23 to a vertical position, the clamping cylinder I 13 of the upper clamping lifting device 2 extends, driving the roller assemblies 10 at both ends to extend and clamp the A tubing string 8, the hydraulic motor 15 drives the diamond roller 17 to rotate, the diamond roller 17 drives the A tubing string 8 to move downward, after the coupling of the A tubing string 8 passes the lower clamping lifting device 5, the clamping cylinder I 13 of the upper clamping lifting device 2 gradually retracts, and the lower clamping lifting device 5... Device 5 clamping cylinder I13 gradually extends, and the clamping force electrical signal reflected by the weighing sensor 19 ensures that the upper clamping lifting device 2 and the lower clamping lifting device 5 can smoothly complete the clamping handover of pipe column 8. The lower clamping lifting device 5 drives pipe column 8 to move downward into the pre-set hole in the ground. The coupling position of pipe column 8 is at the punch clamp 34 of the fixed iron drill 4. The lower clamp of the punch clamp 34 clamps the coupling of pipe column 8, and the lower clamping lifting device 5 releases pipe column 8. Using the same process, another B-column 8 is transferred to the coupling position of the previous A-column 8. The telescopic arm 21 of the pipe-supporting robot 3 flips to a horizontal position and extends. The pipe-supporting wrench 20 grasps the B-column 8, and the screw-locking pliers 33 of the fixed iron drill 4 clamps the B-column 8. The upper clamping lifting device 2 releases the B-column 8, and the screw-locking pliers 33 rotates to screw the coupling threads of the two pipe columns 8 together. The snap-locking pliers 34 clamps the coupling of the two pipe columns 8 to perform a tight-locking operation, completing the establishment of two single-column, one-column pipe columns. To complete the establishment of three single-column, one-column pipe columns, only one additional pipe column connection needs to be added using the same method. After the standpipe is erected, the pipe lifter hoists the standpipe from the pipe string erection device by lifting the coupling of the pipe string 8. The pipe support manipulator 3 supports the lower part of the pipe string 8. The pipe support manipulator 3 extends and retracts via the lifting cylinder II 25, driving the main boom 23 to slide up and down within the guide rail frame 24 to meet the required lifting height for the pipe string 8. Through the rotation of the slewing device 26, the telescopic boom 21 extends to support the pipe string 8. With the pipe lifter, the standpipe is delivered to the wellhead and connected to the drilling string for normal drilling. To accommodate pipe strings 8 of different lengths, the lifting cylinder I 7 extends and retracts, driving the upper clamping lifting device 2 to slide up and down the mounting frame 1, adjusting the relative positions of the upper clamping lifting device 2 and the lower clamping lifting device 5. The process of disassembling the standpipe is the reverse of the process of establishing the standpipe. After drilling is completed, the pipe lifting robot lifts the standpipe to the standpipe establishment device, disassembles it into a single pipe string 8, and the vertical pipe delivery robot grabs the single pipe string 8 and sends it into the vertical drill pipe box.
[0025] This invention relates to a root-establishing device with roller-clamped tubing string lifting and lowering function, solving the problems of existing technologies involving multiple processing devices, complex control processes, low processing efficiency, and disruption to normal drilling. A vertical tubing delivery robot grabs the tubing string from the drill pipe box and transports it to the root-establishing device. The root-establishing device, through functions such as clamping, lifting, attaching / unattaching, and tubing support, establishes the tubing string. This device has a high degree of functional integration, enabling a single unit to complete the tubing string connection and disconnection work, thus improving processing efficiency. Through local operation and remote operation by the driller, the vertical tubing delivery robot, vertical drill pipe box, and root-establishing device are linked and controlled, achieving automation of the entire process.
